Print image and record audio input

I am very green about programming but wish to learn and develop.

I want to write a simple application that will be useful in linguistic treatments - but at first it is simple demo.

The application is about to display image and record sound during projection. There are few variables - interval and image/sound/movie clip paths - taken from external txt file (for the beginning - later I would like to perform some creator with presaved configurations).

The config file now looks like:

10
path1
path2
...

The first line is about to input interval in seconds, next there are paths to images, sounds or movie clips (I tried with images for now).

When asked few programmers about the code it is as simple as riding a bike, so I wanted to learn how to write it by myself.

I guess it is peace of cake for professionals - 1000s of thanks to these ones who want even to read this junk.

It takes a lot of time for me to understand and figure out the exact commends that is why I am asking politely about the help - not only for education but also for better diagnosis.

Excuse me for the language - English is not my native language.
